标题： Quantum Gravity and Phenomenology: Dark Matter, Dark Energy, Vacuum Selection, Emergent Spacetime, and Wormholes

摘要： 我们讨论了量子引力与高能现象学前沿问题的相关性：暗物质问题、暗能量问题以及真空选择问题，以及与新兴时空和虫洞相关的问题。 在作为量子引力模型的弦理论背景下，讨论了暗物质和暗能量现象学以及真空选择问题。 在量子引力有效理论的更广泛背景下，讨论了新兴时空和虫洞问题。 显示英文摘要

摘要： We discuss the relevance of quantum gravity to the frontier questions in high energy phenomenology: the problems of dark matter, dark energy, and vacuum selection as well as the problems of emergent spacetime and wormholes. Dark matter and dark energy phenomenology, and the problem of vacuum selection are discussed within the context of string theory as a model of quantum gravity. Emergent spacetime and wormholes are discussed in a more general context of effective theories of quantum gravity.
